The Apple portable media player, iPod sixth generation, was introduced in September 2008 with the “Classic” suffix the received a new interface design and an anodized aluminum front plate. The hardware and the firmware were updated with a 120GB model, replacing a previous 80GB model and the 160GB model was later discontinued. The one depicted is a 160GB model.
Many of my tomato plants are showing some red coloring on the bottom of their leaves and in the stalks. I've been reading that this indicates a phosphorous deficiency. I planned all along to add rock phosphate to my garden (to give the plants phosphorous). I had figured that the compost in the soil I used for these plants would have enough nutrients until then. It seems that I am wrong, so I'm giving the plants a little liquid fertilizer now.

Victory over the Blue Sky charger! A simple fuse replacement after hours and hours of angst and troubleshooting.
This is a personal side/weekend project: a work-in-progress remake of an old PC game I've been creating in-browser, and a general exercise in OO-JS design and performance testing.
This is a screenshot from an old WinXP laptop, also a good testing candidate: It's a 2006-era Fujitsu notebook, 1.2 GHz CPU, 512 MB of RAM and an Intel 915-series GMA graphics card.
Garbage Collection can interrupt your script execution, meaning jank and/or dropped frames and reduced performance in your web work - so it's helpful to reduce the amount of "garbage" you create in the first place.
In this case, there was an expensive loop within the collisionCheckArray() function with a lot of calls and many iterations and due to inefficient design, it was making a local copy of a {x, y, width, height}-like parameter object on each call so it could be modified without affecting the original object.
The copying resulted in a lot of temporary objects being created, contributing to nearly 20 MB of RAM being used overall before GC (or other de-allocation / memory freeing routines) kicked in and brought the levels back down.
As a quick test, simply shunting the collisionCheckArray() function via return: false; proved that it was one of the big contributors to memory use.
The screenshot above shows the memory graph over time while running the game, before and after the "shunt".
The proper fix involved storing the "extra" collision data on the object being passed into the function, eliminating the cloning and just passing by reference - which in retrospect, is now pretty obvious.

Alaska brand liquid fertilizer that I bought at Lowes today. The fish emulsion is certified as organic. The Morbloom is not, but I found both under the "natural and organic" section, so I figured it was good enough. I gave each tomato plant about 8 ml of diluted Morbloom today.
Need to Reset PMU? The iMac was a dramatic departure from mainstream computer design. The design of the first generation of the iMac has been credited to Jonathan Ive, currently Vice President of Industrial Design at Apple. It was the first computer to ship with out a floppy drive and was equip exclusively with USB port standard. The slot-loading iMac G3 began shipping in late 1999 with additional DV (Digital Video) designation. This version had FireWire, CD-RW/DVD-ROM, 500 Mhz Processor atop the new "Pangea" motherboard with a 16MB ATI Rage 128 Ultra graphics chip. The 2001 series was available in indigo, graphite, and snow with either the 500, 600, or 700MHz (PPC750CXe) processor.
More tomato leaves with reddening; I'm pretty sure that this indicates a phosphorous deficiency. This is an Anna Russian tomato plant. Whenever it isn't happy, it goes all limp and falls over. It also has a bad case of red leaves. I hope the Morbloom fertilizer that I gave it will help. He is growing like crazy though. I've read in forums that Anna Russsian looks pretty lame most of the time but still gives off a good harvest. Time will tell.

We had a meeting with all the faculty of APU's educational technology meeting. Most people would dread an all-day Saturday meeting. I, however, always look forward to them. There are so many great minds (from San Diego to Ventura) that come together... good ideas always result.

I made this while troubleshooting a series of bugs in a piece of software I recently acquired. I'm happy with these results because I'd shot them deliberately overexposed using the ETTR approach. The Sony and UFRaw software failed miserably to recover information in the highlight areas. So I abandoned the ETTR approach. Looking at these new images I can see that I can start using ETTR again.

Busy evening. Job application stuff and interview scheduling. So, naturally, I felt like adding iPhone troubleshooting. Remember five days ago when my iPhone messed up? Well, it happened again. Grrr. So a normal restore from backup didn't help. Time to just restore as a new phone. Alas, the problem seems fixed (fingers crossed), and I had to spend a lot of time re-organizing and logging back in to a bunch of apps.
...downside: all the photos and video taken by my iPhone are now gone. I hadn't backed them up to iPhoto in a long time. Why? Bacause I barely use iPhoto. iTunes should just put all photos into iPhoto automatically. Oh well.
Fresh start.

A while back we covered some troubleshooting solutions to speaker problems that we hear about all the time. For this article, we’re going to focus on home theater issues that are the result of folks not always making the best choices. If some of these examples look a bit familiar, fear not, they will all be easily remedied by following our recommendations. Let’s dive in and start tackling the obstacles and finding fixes!
1. Placing Tower Speakers Too Close to a Wall
Take a look at this Verus II Grand set up, it looks amazing right? Indeed it does, but there’s one minor issue that can be quickly addressed to improve its performance, which is the placement of the left tower. It’s nearly touching that sidewall and because of that, the bass is probably reverberating too much and the speaker likely sounds muddy. Basically when a tower speaker, or any speaker with a good amount of bass, is too close to a wall, you start to hear the room vibrate instead of the sweet, sweet music coming from the speaker. For a rear ported tower speaker like the Verus II Grand, you really want to give it at least a foot on all sides from any walls and if you can, two feet is even better. For front ported speakers like the Intimus 4T and 5T, you still want to give them at least a foot, because sound will still wrap around the cabinet from the front. The absolute worst thing you can do is to place your front speakers in a corner or alcove. People get tempted to place their TVs in a corner in open floor plans, but it’s a recipe for your front speakers to be too close together. When front speakers aren’t properly spaced apart, you lose stereo imaging and the 3D spaciousness that a correctly set up stereo system can provide. Instead of a realistic soundstage with each instrument having space to breathe, things can sound compressed and undefined. On top of that, the corner walls will really increase the dB level of the bass frequencies. In fact a corner can increase the bass response of a speaker by up to 16 times! So you can see how placing your fronts in a corner is a bad idea that can easily result in a very unbalanced sound.
2. Other Non-Ideal Speaker Placement
Beside placing a tower speaker away from a wall, there are some other rules of thumb to follow when you are positioning speakers in your room. An extremely common impulse we see is for folks to place their center channel pushed back on a shelf. Whether they are concerned with knocking the speaker off the shelf or just like the way it looks with the speaker pushed back, people often times don’t place their speaker on the edge of the shelf initially. But you don’t want to leave any empty shelf in front of a center channel because the reflections off the hard surface in front of the speaker will cause a peak in the midrange and de-emphasize the other frequencies.
Another common placement people attempt when they have difficult rooms is to put their surrounds in front of their seating position. Now you can place the surrounds ever so slightly in front of you, a few inches if you have to, but anything more than that and you will start to lose the surround effect of the speakers. Once the surrounds are a couple feet in front of you, the sound fields between them and the fronts begin to merge and you only perceive two speakers instead of four. Sure sounds coming from the surrounds may be a bit louder because they are closer, but you will not hear sounds as they are moving between the speakers any longer.
3. The Battle Between TV and Center Channel
It’s the age old conundrum, the ideal placement for your TV is eye level and the best placement for your center channel is ear level. Well, bad news, it turns out that your ear and eyes, at least for most of us humans, are roughly at the same level. Because of this, you either see TVs placed way too high, which is frequent when it is placed over a fireplace, or you see center channels that are either too high or too low. Bearing in mind that there will need to be some compromise between the two, the best placement option is to have the TV at eye level and the speaker just below it or conversely the center channel at ear level and the TV just above eye level. No matter what you do though, don’t place everything several feet off the ground as you’ll end up with not only a sore neck from looking up, but also subpar dialog intelligibility. Or hey, maybe go for this placement if your goal is to stop watching so much TV and to go outside once in a while. Just kidding, we would never recommend that!
4. Buying Speakers Without an In-Home Audition
We hear about it all the time from people we talk to, the speakers they purchased sounded absolutely incredible when they listened to them at the store, but not once they were installed in their home theater. It sounds obvious, but the demo rooms in stores have been specifically designed and treated to make speakers perform optimally. By contrast, if you are just listening on the floor of a big box store, there’s so much background noise that who can say how the speaker really sounds? In both instances, the listening environment is going to be nothing like your home. Without a doubt, home speakers that you hear at a store will sound drastically different once you get them in your own home due to the size of your room, placement, furniture, electronics, floor material and ceiling height, just to name a few factors. In fact, your room is a larger part in affecting your speakers sound than the receiver or amp you use! We do it too, here at the Aperion Audio showroom, we’ve spent a large amount of time placing and calibrating our speakers and electronics, as well as adding room treatments to quiet the space in order make sure our speakers sound their absolute best. But the difference with our business model is that getting the speakers home and setting them up is just the beginning of the audition process. With our 60 day in-home audition, you’ve got plenty to time to listen and make any adjustments needed in placement or even try out different receivers and amplifiers if you’re a real gearhead with more than one laying around. It can’t just be us with “spare” receivers waiting in the wings, right?
5. Buying an Underpowered Receiver
This is an easy trap to fall into because so many manufacturers play games with the specs. In fact, we recently even dedicated an entire blog to sorting out how much power a receiver will provide in the real world. Also, many of the reviews out there focus on video processing and features, but don’t really provide much evaluation in terms of sound quality. These reviews may lead you to buy a receiver with all kinds of bells and whistles while lacking a quality amplifier section. But a lot of times folks just don’t set aside enough budget for the receiver. Considering that your receiver controls how everything looks and sounds in your setup, it definitely doesn’t pay to skimp on this link of the chain. Put it this way, if you’re thinking of buying a 5.1 or 7.1 system in the $2K-$4K range as many of our systems are, a $400 receiver is not going to allow the true quality of the speakers to shine through. A good rule of thumb is that most of the receivers that can really power a system a well will start in the $700-$800 range and to really get a beefy receiver that will provide all the juice your speakers crave, you should consider spending $1000-$1500.
Another route you can take is to buy a receiver with pre-outs and then power your fronts and possibly center with an external power amp. While a separate power amp will get much more power to your speakers, keep in mind that you’ll be spending north of $2500 for a setup like this.
6. Not Calibrating Your Receiver and TV
You’ve come this far, you did your research and got the perfect speakers, receiver and TV, but make sure you don’t skip the last step, calibrating your system to get the most out of it! As far as the receiver goes, almost all of them include some form of auto setup software. Now sometimes you can get better results from a manual set up, but the auto set up is definitely a little quicker and can also do a very good job. If you do use the auto set up feature of your receiver, make sure you follow the instructions for the microphone placement, as this is critical. Placing the mic on the back of the couch isn’t the best option as any obstructions can affect the quality of the test tones it needs for setup. Use a tripod if possible and place the tip of the microphone exactly where the listener’s head will be when sitting down. Use as many mic positions throughout the room as you can so that the software can accurately measure the acoustic properties of your room. One last tip, when using the auto set up, turn the level of your subwoofer down to maybe 1/3 or ½ volume and always double check your channel level when the calibration is done. If you see large variances in volume level, especially from the surrounds or subwoofer, chances are you didn’t get a clean reading and should try again. If you do go for a manual set up, you can find some tips for adjusting the settings here.
As for the TV, these days some calibration is something you simply must do. At the very least you’ll want to turn down the brightness that they use for in-store demonstrations and turn off the dreaded “soap opera” effect aka motion smoothing. Beyond that, it’s a good idea to go through each of the settings in your TV and to adjust them to your viewing conditions and preferences. If you want something a bit more technical, but also more generic, you can search for your model’s ISF settings and use those recommendations to dial in everything. Spend a little time making either your own adjustments or use the ones from ISF and you’ll be amazed at just how much better your display will look.
7. Listening to or Watching Low Quality Source Material
Finally, once you’ve calibrated your system and everything is ready to rock, pay attention to what you are going to be running through it! We hear about people that are having issues with audio and video quality all the time and it turns out they are either listening to low quality mp3s or just watching broadcast TV. Especially if you are watching standard definition TV on an HDTV or 4K display, it’s going to look pretty terrible. Remember, your system is only as good as its weakest link and that goes for the material you watch and listen to as well. You’ve spent the time and money on your gear, make sure that the sources are high quality too! Stick to HDTV and Blu Ray for your TV and CDs, SACD or lossless audio downloads for music.
Now that you now what not to do, go forth and enjoy the best that your system has to offer and as always, happy listening!

More performance troubleshooting with Chrome DevTools. At this point, I've either found a bug or I'm doing something wrong; I suspect the latter.
Using the Timeline, I record gameplay and fire 64 rounds of the machine gun. This results in JS object and DOM node creation. Once those objects die, they should clean up and remove both DOM nodes and JS references to the nodes. The expected result is that the next GC event should free resources used by the nodes and JS objects.
What is observed is somewhat different: There is a linear growth in the DOM Node Count graph, with no drop even after a forced GC event.
However in the Heap snapshot view, you will note that the Document DOM tree represents a total of 904 nodes, only two more than when I began recording (and before adding 64 nodes via the machine gun firing.) Additionally, if nodes were indeed leaking, I would expect to see those under "Detached DOM tree" entries in the Heap snapshot view - and those are not shown.
It appears there is a disconnect between the DOM Node Count and the Heap snapshot, possibly a bug, and/or I'm doing something wrong.

I originally purchased this TechStep to diagnose problems I was having on one of my SE/30 logic boards (even after replacing the capacitors, it still shows only horizontal lines all the time). There is also a SCSI card that has special diagnostics for that interface port. Unfortunately, my SE/30 board appears to be too badly damaged as even this TechStep cannot provide me data on what is wrong with it.
The 4 ROM modules I have are:
1. CPU Tests, Vol. 2, v. 1.0
2. CPU Tests, Vol. 1, v. 1.1.1
3. CPU Tests, Vol. 3, v. 1.0
4. SCSI HD Tests, v. 1.0
Extensive information on the TechStep, as well as photos of the circuit board can be found on YouTube here and on this website.
